Open Source Kanban Board
A kanban board is honest in a way other planning tools aren't: the columns make work-in-progress visible, so when one column is jammed the bottleneck is sitting right there on the wall instead of buried in a status report. The open source boards below give you that visual flow without metering you per column or card, and they keep the board state in storage you control, so a wall your team reads every morning can't be paywalled or shut down out from under you.
